Replaces the underlying address.

1) Replaces the underlying address with a null pointer value. After assignment, * this does not refer to a coroutine. This assignment operator is not declared for specialization std:: coroutine_handle < std:: noop_coroutine_promise > .
2,3) Replaces the underlying address with the one of other . Copy and move assignment operators are equivalent to implicitly declared ones.

Parameters

other - another coroutine_handle to assign from

Return value

* this
